<h2>Answers:</h2>

a. 3 : 5 = 12 : 20

12 is four times 3, so multiply 5 by 4. (5 × 4 = 20)

b. 4 : 9 = 12 : 27

27 is three times 9, so multiply 4 by 3. (4 × 3 = 12)

c.  8 : 7 = 16 : 14

14 is two times 7, so divide 16 by 2. (16 ÷ 2 = 8)

d. 2 : 3 = 3 : 4 (?)

3 is one higher than 2, so add 1 to 3. (3 + 1 = 4)

A big-screen TV that previously sold for $2,400 has been marked down to $2,040. What is the percent of decrease?
Hitman42 [59]

[~Answer~] (8.):
Heyyy. I'm Avery, and I'm always here to help!

I believe the percent may be 15% ($2,400 - 15% = $2,040)

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

[~Answer Explanation~}:

The percent of the difference is the rate of the difference * 100%

the percent of the difference = .15 * 100% = 15%

since the new price is less than the old price, that is the percent of the decrease.

(See if it'll work): $2,400- 15% = $2,040

And there's your answer <33

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
